Reports FAQs and Troubleshooting
A.
The As Of column indicates the starting time of the aggregation for the utilization report. Therefore,
the starting time shown might be earlier than the date range selected for the report.
Q.
How long can report data be kept in WLSE?
A.
the trends reports data is kept in the WLSE database for a specific amount of time, which can be
configured (see Devices > Discover > Inventory > Polling).
Q.
The SSID field in the Manage Rogues > Rogue AP List report is being displayed in hexagonal
format (for example, "\x00\x00\x00\x00\x00\x00\x00\x00\x00"). What causes this?
A.
If the SSID contains unprintable characters, the WLSE displays it in hex notation. In this example,
the SSID is set to 9 hex zeros.
The WLSE displays unprintable characters as \xNN, where NN is the hex value of each character,
followed by the length of the SSID in bytes. For example, “\x00” [1] means that the SSID contains
the hex value \x00 and is 1 byte long. In addition, any double quote marks or backslashes that are
part of the SSID octets are displayed using a preceding backslash (for example, \" or \\).
Q.
Why is the device information in the reports under Device Center not displaying properly when I
view them with a Firefox browser?
A.
Firefox does not support line breaks or long text (maximum 50 characters).
